The mobility of the future depends not only on autonomous or electric vehicles, but also on the infrastructure that accompanies them. Smart roads, also known as smart roads, represent a key advance in the transformation of transportation: connected, sustainable, and adapted to current needs.
In this guide, we explore what they are, what technologies make them possible, and how companies such as Viarium are leading its development.
What are smart roads?
Smart roads are road infrastructures designed to collect, process, and share data in real time with the aim of improving transport safety, efficiency, and sustainability.
These roads integrate sensors, advanced connectivity, and automated systems that enable communication with vehicles, control centers, and other elements in the environment.
Its main objective is to anticipate traffic needs, reduce risks, minimize environmental impact, and offer a smoother and safer driving experience.
Smart roads are part of the smart city ecosystem and the smart mobility, where mobility becomes a service tailored to each user.
Benefits of smart roads
The implementation of smart roads brings significant advantages for both public administrations and road users. The main benefits include:
- Improved road safety: early detection of accidents, obstacles, or adverse weather conditions.
- Efficient traffic management: real-time analysis to adjust traffic lights, detours, or speed limits.
- Reduction of pollutant emissions: optimization of vehicle flows and prioritization of electric transport.
- Predictive maintenance: sensors that alert drivers to potholes, wear and tear, or structural problems before they become critical.
- Connectivity with autonomous vehicles: support for automated driving through digital signals and V2X (vehicle-to-everything) communication.
These advantages enable the creation of efficient, resilient, sustainable, and future-proof infrastructure.
Technological innovations in smart roads
The development of smart roads is based on the integration of various emerging technologies. Below, we review some of the most relevant ones:
Big Data
The massive collection of data on speed, traffic flow, pavement conditions, and weather allows authorities and operators to make informed decisions. Real-time Big Data analysis facilitates pattern detection and improves traffic management and road maintenance.
Drones
Drones are key tools for road inspection and monitoring. Their use allows for the detection of incidents, 3D mapping, construction site monitoring, and structural damage assessment after weather events. Their speed and low operating costs make them strategic allies.
Blockchain
The use of blockchain guarantees the security and traceability of data collected on smart roads. This technology allows for decentralized management of information on maintenance, incidents, and access rights, increasing transparency and reducing administrative errors.
BIM (Building Information Modeling)
The use of BIM in road infrastructure planning and management allows the behavior of the road to be simulated under different conditions, optimizing resources and facilitating long-term maintenance. Thanks to 3D modeling and associated information, the entire life cycle of the infrastructure is streamlined.
5G connectivity
5G technology is the basis for instant communication between roads, vehicles, pedestrians, and control centers. Thanks to its low latency and high capacity, it enables the implementation of real-time services, from dynamic signage to coordinated autonomous driving.
The role of Viarium in smart roads
In Viarium, we understand the smart roads as a necessary step toward safer, more sustainable, and efficient mobility. Our approach combines advanced engineering, technological innovation, and sustainable vision to lead road transformation projects.
In addition, we collaborate with administrations and technology companies to promote pilot projects and develop regulations that favor the expansion of smart roads in the European and Latin American contexts.
